Source code for cosmetic_changes
"""This module can do slight modifications to tidy a wiki page's source code.
The changes are not supposed to change the look of the rendered wiki page.
If you wish to run this as an stand-alone script, use::
scripts/cosmetic_changes.py
For regular use, it is recommended to put this line into your user config::
cosmetic_changes = True
You may enable cosmetic changes for additional languages by adding the
dictionary cosmetic_changes_enable to your user-config.py. It should contain
a tuple of languages for each site where you wish to enable in addition to
your own langlanguage if cosmetic_changes_mylang_only is True (see below).
Please set your dictionary by adding such lines to your user config::
cosmetic_changes_enable['wikipedia'] = ('de', 'en', 'fr')
There is another config variable: You can set::
cosmetic_changes_mylang_only = False
if you're running a bot on multiple sites and want to do cosmetic changes on
all of them, but be careful if you do.
You may disable cosmetic changes by adding the all unwanted languages to
the `dictionary cosmetic_changes_disable` in your user config file
(`user-config.py`). It should contain a tuple of languages for each site
where you wish to disable cosmetic changes. You may use it with
`cosmetic_changes_mylang_only` is False, but you can also disable your
own language. This also overrides the settings in the dictionary
`cosmetic_changes_enable`. Please set this dictionary by adding such
lines to your user config file::
cosmetic_changes_disable['wikipedia'] = ('de', 'en', 'fr')
You may disable cosmetic changes for a given script by appending the all
unwanted scripts to the list cosmetic_changes_deny_script in your
user-config.py. By default it contains cosmetic_changes.py itself and touch.py.
This overrides all other enabling settings for cosmetic changes. Please modify
the given list by adding such lines to your user-config.py::
cosmetic_changes_deny_script.append('your_script_name_1')
or by adding a list to the given one::
cosmetic_changes_deny_script += ['your_script_name_1',
'your_script_name_2']
